• Inhalation Risk: A nuisance-causing concentration of airborne particles can be reached quickly when dispersed.
• Effects of Short Term Exposure: May cause mechanical irritation.
• Description: Calcium stearate is an organic calcium salt of stearic acid. It is utilized as a component in lubricants and surfactants.
• Composition: Chemical Formula: Calcium stearate is represented by C36H70O4.Ca or C36H70CaO4.; Octadecanoate Component: It contains an octadecanoate component.
• Application in Concrete: Damp-proofing Admixture: Calcium stearate serves as a damp-proofing admixture in concrete to restrict water and aggressive ions' ingress.; Water-Repellent Layer: It forms a water-repellent layer along the capillary pores, reducing permeability under non-hydrostatic conditions.
• Lightweight Concrete: Hydrophobic Properties: Calcium stearate is hydrophobic and can provide a water-repellent layer in lightweight concrete, reducing pore filling and cracking.; Density Reduction: A high dosage of calcium stearate increases air content and reduces the density of lightweight concrete.
• Surfactant Properties: Anionic Surfactant: Calcium stearate acts as an anionic surfactant in cement-based materials.; Water Repellency: It provides a water-repellent layer along the capillary pores, reducing concrete permeability under non-hydrostatic conditions.
• Additional Benefits: Corrosion Reduction: Calcium stearate significantly reduces corrosion attacks in concrete.; Efflorescence Control: It controls efflorescence in brickwork, serving as a water-repellent, air-entraining agent, and efflorescence controller simultaneously.
• Pyrolysis: Hydrocarbon Generation: Pyrolysis of calcium stearate produces hydrocarbons, CO2, CaO, CaCO3, coke, and other inorganic compounds.; Yield: The maximum yield of methane generated from calcium stearate is comparable to that from North Sea oil.; Mechanism: Hydrocarbon generation from calcium stearate involves cracking of the alkyl moiety, similar to pyrolysis of n-C18.
